LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 534,591, dated February 19, 1895.

Application filed October 28, 1893. Serial No. 439,413- (No model.) 1 I To all whom it may concern.-

Be it known that we, MILO BROWN WIBLE and HENRY DANIEL PRESSEY, citizens of the United States, residing at Arcata, in the county of Humboldt and State of California,

have invented a new and useful Automatic Lubricator, of which the following is a specification.

This invention relates to lubricators; and it has for its object to provide certain improvements in lubricators of that character wherein the oil is displaced by a hydrostatic pressure or water column.

To this end the main and primary object of the invention is to effect certain improvements in automatically operating lubricators of the character noted, whereby the same will be rendered more efficient for use in lubricating the interior working parts of steam engines and similar machinery, and also to provide a lubricator in which overheating of the lubricator proper is avoided and the sight glasses are always kept clear, and also whereby the steam employed in connection with the lubricating device is caused to escape out of the break, should any occur.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the drawings, Figure 1 is a front elevation of a lubricating apparatus constructed in accordance with this invention, shown applied to the live steam pipe of an ordinary engine, one end of the cylinder of which is shown. Fig. 2 is an enlarged detail sectional view of a portion of the apparatus showing particularly the relative arrangement and construction of the steam and oil pipes.

Like numerals of reference indicate corresponding parts in both figures of the drawings.

Referring to the accompanying drawings, the numeral 1 designates a cylindrical or other suitable shaped oil supply tank, which is adapted to contain the oil to be fed to'the lubricating device proper, as well as to receive the condensed steam or water which is employed for displacing the oil and feeding it to the parts to be lubricated. The oil-supply tank 1 may be provided at both ends thereof with suitable ears or lugs 2, which receive bolts or screws for clamping the same to the engine bed 3, or other convenient point of attachment, and said oil-supply tank 1 is further provided in the top thereof with the plugged filling opening 4, through which the oil is introduced when the tank 1 is being filled, and the latter is further provided in the bottom thereof with the valved waste-cock 5,

by means of which the condensed steam or I water may be drawn out of the tank when the same has been emptied of the oil by the feeding thereof to thelubricator proper. The main oil-supply tank 1 is also provided in the top thereof with an oil-discharge opening 6, into which is fitted the lower end ofthe oil-feed pipe 7.

The oil-feed pipe 7 extends a suitable distance above the tank 1, so as to be properly connected to the lubricator part of the apparatus, and it has connected to the upper end of the coupling head 8, which head is provided with a filling opening 9, which may be used instead of the opening 4, for the purpose of refilling the tank 1, with oil after the same has been emptied, and the said coupling head 8 has connected to one side thereof one end of the connecting pipe 10, which is coupled to and fits into the upper end of the ordinary sight-feed lubricator or secondary oil reservoir 11. 4

The sight-feed lubricator 11 may be used in connection with any machinery to be lubricated,- but as illustrated in the present invention, the same is connected to the live steam pipe 12, which leads into an engine cylinder 13, and means are thus provided for introducing oil into the engine cylinder, Whereby the interior working parts of the engine may be properly lubricated.

A steam supply pipe 14 is coupled to the engine steam pipe 12, at a suitable point above the lubricator 11, and is provided with a valve 15, which provides means for regulating the flow of steam through such pipe. The said pipe 14 projects through the coupling head 8, at the upper end of the oil feedpipe 7, and extends inside of said oil feedpipe 7, the entire length thereof, to a point inside of the top of the supply tank immediately below the connection of the pipe '7 thereto, and said steam pipe 14, is provided at its lower extremity with a curved upturned seal bend 16, which is useful in providing means whereby the condensed steam or water in the lower portion of such pipe will not run entirelyout of the same when the oil-supply.

tank 1 is being refilled, and also to provide means for directing the escaping steam up through the pipe 7, should any breakage occur in the apparatus, thereby permitting such escaping steam to find vent through the break, wherever it may be. 7

By reference to the drawings it will be noticed that the up-turned seal bend 16 of the pipe 14, together with the pipe 14:, do not occupy a space greater'than the diameter of the pipe 7, so that the upper discharge end of the bend 16 shall be located within the area of the oil feed pipe so as to discharge directly thereinto.

From the foregoing it is thought that the construction, operation and advantages of the herein described lubricating apparatus will be readily apparent to those skilled in the art. After the oil-supply tank 1 has been filled with the liquid or oil, either through the opening t or 9, steam is turned into the pipe 14 through the valve 15, and condensing before reaching the bottom of the tank 1, the water of condensation accumulates in the bottom of said tank and displaces the oil therein, causing the same to rise up the pipe 7 and to be fed into the sight-feed lubricator 11, from which it is carried to the point of use, which is illustrated to be an ordinary engine cylinder.

By the employment of the tank 1 a large supply of oil is always available for the lubricating device, while at the same time it is almost impossible for steam to get to the lubricator, thereby providing means for always keeping the sight glasses of the lubricator clear, and in the event of a break in the lubricator the disposition of the lower upturned bend 16, of the pipe 14, directs the steam up the pipe 7 and allows it to escape out at the break, and at this point it may be well to again observe that the bend 16 will providea water seal at that point, when the valve 15 is closed and the tank 1 is being filled with oil, so that all the water will not run out of the pipe 14:.

hen the apparatus is in operation it will of course be understood that the oil is forced through the lubricator 11 and into the pipe 12 in small regulated quantities, and there is therefore necessarily an appreciable resistance to the free flow of oil through such lubricator. For this reason a similar resistance is given to the passage of the steam out of the pipe 14, so that the. steam in such pipe will have an opportunity to condense before reaching the bend 16 and provide for the operation of the apparatus. Now in the event of an extreme break occurring in the lubricator 11, there will be no further resistance to the free flow of oil up through the oil pipe 7, and the column of oil contained in such pipe will be forced out through the break in the lubricator, and at the same time no-=further resistance being Offered to the steam inthe pipe 7 the same passes out through the bend 16, and follows the oil up through the pipe 7 and out of the break. By thus directing the steam, the oil that remains in the tank 1, will be undisturbed, Otherwise such remaining oil would also'be blown out of the tank.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described our invention,what we claim, and desire to secure by Letters Patcut, is- I The combination in a condensation dis placement lubricator; of a suitably arranged oil supply tank provided in its top with a filling opening and an oil discharge opening, an upright oil feed pipe fitted at its lower end into the oil discharge opening of the oil supplytank, a secondary oil reservoir, a pipe connection between the upper end of the secondary oil reservoir and the upper end of said oil supply pipe, said oil supply pipe being closed at its upper end, and a smaller valved steam pipe arranged longitudinally inside of the larger oil feed pipe and extending throughout its entire length, said smaller steam pipe being provided at its lower end in the top part of the oil supply tank with a short upturned seal bend 16, the upper discharging end of said bend being located within the area of the oil feed pipe and disposed in a longitudinal line therewith so as to discharge steam thereinto in a direct line with the length thereof in the event of a breakage in the secondary oil reservoir, substantially as set forth.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presenceof two witnesses.
